UNITED STATES PATENT OFFICE.

XVILLIAM YVILSON, OF PINE GROVE, NEVADA.

SPECIFICATION forming part of Letters Patent No. &63,239, dated November1'?, 1891.

Application filed J une 13, 1891.

To all whom it may sondern.-

Be it known that I, WILLIAM'WILSON, a citizen of the United States ofAmerica, residing at Pine Grrove` in the County of Esmeralda and Stateof Nevada, have invented certain new and useful Improvements in Picks,of which the following is a specificaton.

My invention is an improvement in picks, and I aim to provide by it asimple form of head in which the pick proper maybe securely held,thehead in turn being Secured to the handle.

I have shown my invention in the accornpanying drawings, in which-Figure 1 is a perspective View of the picksocket. Fig. 2 shows the samein section With the pick in place.

A In the drawings the handle of the pick is shown atA. Its lowerendispreferably made tapering and is adapted to be forced into thetapering socket B. This sooket is open atone end to receive the handleof the pick, and this opening extends entirely through the socket,except at the sides, where overlapping edges l are left, and these edgesserve as a hearing for the support of the wedge and for the end` of thepiok-handle and to prevent the handle in its insertion in the socketfrom being forced through beyond this point. Extending from the sidewalls of the socket is a loop O, of less width than the socket proper,this loop having an opening through the same to receive the pick' D andits looking means. The closed end of the loop on its inner face ispreferably formed slightly concave, so as to receive the correspondingface of the pick, as ordinarily the rear face of the pick is made on acurve. Between the inner faceof the pick and the line of the socketproper a wedge is inserted, as at E, this wedge resting upon theshoulders a of the socket proper, formed Serial No. 396,l6l. (No model.)

by reducing the width of the loop extension. By forcing this wedge intoplace the pick is held securel y, though capable of ready reinoval bydisplacing the wedge. In order to complete the fastening of the parts,the loop and pick engage each other, the one having a projection x andthe other a socket y to receive the same. This takes np the strain,While the wedge, besides assisting in doing this, also serves to keepthe projection firnly in the sooket.

It very often happens that the pick-handle willbecone broken or worn orfor some other reason it is found necessary to remove it from itssocket, and as it is driven into place without wedges of any kind itwould be diiiicult to remove it unless pressure could be appliedthei-eto from its bottom end. With this in View I extend the opening inthe socket entirely through the same to the reducedwidth of the loopextensionso that when the handle is to be removed I have only to loosenthe wedge and remove the pick, when the bottom of the handle Will beexposed and may be driven out from the socket very easily.

I claim as ny invention- The coinbination of a socket having an openingextending entirely through the same and having a loop extension of lesswidth than the opening in the socket, the extensionopening communicating with the said socketopening, the shoulders a a at the ends ofthe socket proj ectin g inward toward the loop extension to support thewedge, thepiek, and the wedge, substantially as described.

In testim ony whereof I affix my signature in presence'of two witnesses.

i XVILLTAM lVILSON.
